This is the set up of the solar panels at Blackwater National Wildlife Preserve that will be used to power the newly installed sap flow sensors on site. These solar panels will decrease the number of required trips to the site to change batteries and will contribute to the undisturbed data flow from the sensors.

Close up of the newly installed sap flow sensors at Blackwater National Wildlife Preserve. These sensors were installed by EESC's Justine Neville and Ken Krauss of the USGS Wetland and Aquatic Research Center in Lafayette, LA. These sensors will be used to analyze how the trees in a marsh ecosystem respond to changing ecological and climatic conditions.

With the willing help, and creative problem solving skills of roughly 20 volunteers throughout the day,  these two structures emerged. Bolts were tightened down, people quickly figured out what needed to happen and by the end of the day two Hoop House structures were up and almost ready for the clear sheeting that will cover them.
